What Is Hematoma?
A hematoma is a condition in which blood is poured outside the blood vessels. The accumulation of blood within the tissues due to a break in the continuity of blood vessels may be visible as a characteristic lesion on the skin. Hematomas can form on almost any part of the body. The cause of a hematoma is most often trauma, especially in people with a predisposition to bleeding. Certain diseases and specific conditions can increase the risk of hematoma formation.
